DUST-BAG CLOSURE FOR VAGUUiM CLEANERS.

Application filed September 13, 1924. Serial No. 737,618.

This invention relates to improvements in dust bag closures for vacuumcleaners especially although the closure 1s adapted for other uses.

The objects of the invention are:

First, to provide an economical construction for opening and closing adust bag forthe discharge of the dust without detaching the same fromthe cleaner.

Second, to provide such a structure which can be very readilymanipulated and opened and its contents discharged without detaching thebag.

Third, to provide an improved construction" ment of my invention isclearly illustrated in the parts assembled and in locked relation.

the accompanying drawing, this application, in which:

Fig. I is an enlarged detail perspective view of the upper end of avacuum cleaner dust bag with my improved closure in position. the coverbemg open.

Fig. II is a detail end elevation view of the sup orting ring and coverpart, the latch being shown in locked position and dotted at the openingpoint.

' Fig. III is a side elevation view of the structure shown in Figs. Iand II, taken from the right handside of Figure II, the' coversupporting flange and attaching notches be- I ing indicatedby dottedlines.

' Fig. IV is a detail elevation view of these various parts inunassembled relation, the bag andcertain parts being in central verticalsection, the dotted lines showing the relation of parts.

Fig. V

is an enlarged detail sectionalview taken on line 5-5 ofFigs. I, and II,showing Fig. VI is a detail view ot-the opposite side of the parts andstructures in unassembled relation.

forming a part of refer to similar parts throughout the several views,and the sectional views are taken look-. ing in the direction of thelittle arrows at the ends of the section lines. The parts of the drawingwill be considered by their numbers. 1 is a bag, the upper end beingparticularly shown. 2 is the supporting collar for the discharge mouthof the bag. 3 is the carrying ring by which it is attached to the handleof the vacuum cleaner. 4. is the cover with in turned peripheral flange41. 5 is the spring latch for retaining the cover in place. 6 is thecentral pivot therefor.

The bag 1 hasan inturned flap 11- and is re- 7 tained in place on thecollar 2 by the split spring ring 12. The collar 2 is recessed at 21 onits lower face to receive the bag attaching means. The inner side of therecess is flanged at 22 to co-operate with the spring ring and assist inretaining the mouth of the bag in place. The supporting collar 2 isinternally flanged or shouldered at 23 on its outer faceto receive theperiphery of cover 4. Slots 24: are provided for engaging the ends 51 ofthe retaining spring or latch 5. Notches 25 permit the spring 5 to beforced axially in- Ward to engaging position to permit the swinging ofthe ends 51 into the slots 24. The retaining spring is provided withfinger holds 52 to facilitate its manipulation.

The manner of assembly very clearly apears from Fig. IV. The mouth ofthe bag 1s folded inwardly over the split ring 12, which is forced intoplace in the groove 21 on the supporting collar where it engages back offlange 22.. The ring 12 is of spring wire, the meeting ends beingfr'ee.The lever catch 5 is secured in place by the riveted pivot 6 at thecenter, and the ends 51 are adapted to pass into the notches 25 and tobe laterally moved into engagement with the slots 24, something afterthe manner of the retaining means for a photographers printing frame.The ring 3 is provided for connection to the handle support, which is amere incident of the structure.

In use the ring 3 at the upper end of the I bag is readily detached andthe discharge end of the bag is dropped down into discharging The latchlever 5 is then manipuwhich can. be

position. lated and releases thecover 4: very readily manipulated bymeans of the latch as a handle and be readily withdrawn v from the mouthof the bag, leaving a wide In the drawing similar reference charactersopen smooth discharge outlet fully distended or accumulates well towardthe upper or dis charge end, thus in position readily to be dischargedmaking it wholly unnecessary to detach the bag from the delivery nozzlefrom the cleaner.

The improved cover attaching means might be readily used in connectionwith other ends adapted to enter the means for attachment to the upperend of the bag. However, the entire structure is very compact and simpleto manufacture and is readily assembled in the relation indicated. 'Idesire to claim the invention in the specific for-m indicated and alsobroadly as pointed out in the ap ended claims.

Having thus descri ed my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. The combination with the mouth of a dust bag, of a supporting collaror ring therefor provided with a recessed groove on its underfaceprovided with an Lengaging bead, a dust bag with its month end foldedinwardly over a split ring for retaining the same in engagement withinthe recess in said supporting collar, an outwardly faced shoulder,flange within the collar, the collar bein provided with oppositelydisposed inwar ly faced slots notched to receive the cover latch, acover with inturned-flange fitting against the shoulder flange of thesaid collar,

and a spring latch axially pivoted at the center of said cover withoppositely extending notches and engage in the notches in said collar,all coacting as described for the purpose specified.

2. The combination with the mouth of a dust bag, of a supporting collaror ring therefor, an outwardly faced shoulder flange within the collar,the collar being provided with oppositely disposed slots notched toreceive the cover latch, a cover with inturned-flange fitting againstthe, flange of the said collar, and a spring latch-pivoted at the centerof said cover with oppositely extending ends adapted to engage inthe'said slots 111 said collar, coacting as described.

3. The combination with the mouth of a dust bag, of a supporting collaror ring therefor provided with a recessed groove on its under faceprovided with an engaging beaded flange, and, a dust bag with its mouthend folded inwardly over a split ring for retainin the same inengagement withsaid beaded flange within the recess in said supportingcollar, as described.

4. The combination with the mouth of a receptacle, of a collar or. ringtherefor, an outwardly faced shoulder flange within the collar, thecollar being provided with oppositely disposed notchedslots, a coverwith an inturned flange fitting against the flan e of the said collar,and a spring latch axial y pivoted at the center of said cover with opositely extending ends adapted to enter the notches and engage in theslots in said collar, coacting as described.

5. The combination with the mouth of a" flexible bag, of a supportingcollar or ring therefor provided with a recessed groove on its underface provided with an engaging beaded flange, and a flexible bag withits mouth end folded inwardly over a split ring for retaining the samein engagement within the recessed groove in said supporting collar, asdescribed. In witness whereof I have hereunto set my hand.
